At 426, we develop exactly that – solutions that are custom-designed, intelligently implemented and aligned with your specific needs.

With over 10 years of experience in building custom software, we help companies automate processes, connect systems and unlock new digital potential. Our solutions are scalable, secure and future-ready – built with modern technologies and a strong focus on long-term value.
